I hung it next to the chair where we feed Jeffrey at night and he loves it. Every night when we sit down before bed to feed him he looks up and smiles. I also have a fan in the room that I position so that the air flow makes the mobile move constantly. I used braided kite string and a thumb tack to hang it from the ceiling.
I used the easy method for the first one I made but later made the more involved version with the 3D shapes.
